2. Description of the Related Art Conventionally, a power window switch, a power seat switch, and a power door lock switch in a vehicle achieve their respective functions by operating an actuator by a motor. Is driven forward and reverse to adjust the window up and down, adjust the front and rear or up and down of the seat, and lock / unlock the door, respectively. A contact that closes two circuits, a forward rotation circuit and a reverse rotation circuit , An electrode mechanism. A mechanism will be described as an example of such a switch. For example, as shown in FIGS.
A pair of fixed conductive plates 2 are provided in parallel with each other, and contacts 3 are provided at both ends of the fixed conductive plates 2. A swing conductive piece 4 is provided on the fixed conductive plate 2 so as to be swingable. In this case, the pair of fixed conductive plates 2 are alternately arranged. That is, the regulating member 2a is provided near one of the two contacts 3 on the fixed conductive plate 2 so that the contact 3 near the regulating member 2a and the swing conductive piece 4 are intermittently connected. I have. With such an arrangement, under the urging of the leg portion 5a of the operation element 5, the swinging displacement is performed in a swinging manner in a right and left manner,
The two fixed conductive plates 2 and the oscillating conductive pieces 4 are alternately turned on and off to close and cut off the circuit. Also, as in a switch 6 shown in FIGS. 7 and 8, a pair of movable conductive members 8, 8 urged so that one end of the base member 7 resiliently bends.
And fixed contacts 10 and 11 are arranged vertically above and below the one end side, and fixed terminals 10 and 11 are arranged close to each other at positions above and below the contacts 9 and 9 on one end side so as to face each other. The terminals 10 and 11 are provided with contacts 12 and 13 that are in contact with the contacts 9 and 9 of the movable conductive members 8 and 8, and the contact surfaces of the movable conductive members 8 and 8 are formed in a cam shape via a pressing element 14. In some cases, the sliders 15 are alternately pushed by operating means (not shown) to interrupt the contact.

[0003]

However, in the former case, since a pair of fixed conductive plates 2 are alternately arranged on the base member 1, the assembling process becomes more complicated and there is a risk of erroneous assembling. An operator 5 for alternately turning on and off the fixed conductive plate 2 and the oscillating conductive piece 4,
Since the number of components of the leg portion 5a is increased, it is difficult to reduce the size of the leg portion 5a, which leads to an increase in the number of assembling steps, and it is difficult to reduce the manufacturing cost. On the other hand, in the latter, since the pair of movable conductive members 8 are incorporated in the same direction,
Although there is no risk of erroneous assembling, the number of components is still large, including the movable conductive members 8, 8, the presser 14, the slider 15, and the operating means.

The switch 20 shown in FIG. 1 has a configuration in which a pair of movable conductive plates (described later) incorporated in a casing 21 intermittently connect and disconnect contacts by pressing pushers 22a and 22b alternately with an operator 23. In the casing 21,
As shown in FIG. 2, a pair of movable conductive members 24a and 24b urged so that one end is elastically bent is provided. In the vicinity of one end side of these movable conductive members 24a, 24b, contacts 25 are provided above and below, and fixed terminals 26, 27 are arranged above and below these contacts 25 so as to face each other.

The projections 23a and 23b provided on the front side are brought close to each other (see FIGS. 2 and 3). With such a configuration, by operating the operation element 23 by a predetermined angle, the contact 25 near one end of the pair of movable conductive members 24a and 24b is connected to the contacts 28 and 29 provided on the opposed fixed terminals 26 and 27. The switching is performed intermittently by making contact alternately.

According to the switch 20 having the above-described structure, the contact 25 near one end of the pair of movable conductive members 24a and 24b is moved to the fixed terminals 26 and 27 facing each other by the operation of the operating element 23 as one component.
